[Surgical treatment for primary cardiac malignant lymphoma].

A 60-year-old woman who complained of palpitation was diagnosed as ventricular tachycardia on electrocardiography and admitted to our hospital. The ultrasonic cardiography showed cardiac tumor in right ventricle and right atrium. Due to the obstruction of the right ventricle inflow by the tumor, we immediately performed resection of cardiac tumor and repair of right ventricle wall under cardiopulmonary bypass. The tumor was diagnosed as malignant lymphoma by pathological examination for surgical specimen of tumor. After operation her general condition was good, but residual cardiac lymphoma developed large size. We performed radiation therapy for cardiac lymphoma. Therefore the lymphoma was reduced to minimum size. Six months after operation metastatic malignant lymphoma appeared at whole body. So we performed chemotherapy for reduction of systemic malignant lymphoma. At first the chemotherapy was very effective. But metastasis spread rapidly and effectiveness of chemotherapy reduced. Thirteen months after operation she died for respiratory distress, probably due to metastatic brain tumor.
